Answer: C) Neither positive nor negative -- the sum is zero

Adding any positive number to its negative counterpart always leads to 0.

We could come up with a story problem where a person has $37 in their bank account, and then they take out $37 which is represented with the negative number. This leads the balance to become 37+(-37) = 37-37 = 0 dollars.

The sum is zero so neither positive or negative

3.5x-1=-1/2(-7x+2) I know how to solve it which is

Dafna11 [192]

3.5x - 1 = -1/2(-7x + 2)
3.5x - 1 = 7/2x - 1 By virtue of the distributive property
7/2 = 3.5, so there is no solution. The statement is true for any value of x.

Essentially it boils down to -1 = -1, which is always true.

What is 2.318 repeating as a mixed number?

ioda

The idea being, we first, move the repeating part to the left of the decimal point, by simply multiplying it by a power of 10, in this case, we need to move 318, so we need then 1000, 3 decimals, 3 zeros.

and we'll make the expression a variable, so let's do so first,

$\bf \boxed{x=2.318318\overline{318}}\\\\
-------------------------------\\\\
\begin{array}{llll}
1000\cdot x&=&2318.318\overline{318}\\
&&2316+2.318318\overline{318}\\
&&2316+x
\end{array}\implies 1000x=2316+x
\\\\\\
999x=2316\implies x=\cfrac{2316}{999}\implies x=\cfrac{772}{333}\implies x=2\frac{106}{333}$

HELP!!!!!!!!!!!!!!!!!!!!!!!!

Olegator [25]

Answer:

Part) A. Part B and Part C see the explanation

Step-by-step explanation:

Part A) Translate Triangle ABC 6 units horizontally How are the values in the ordered pairs affected by the translation?

If the translation is 6 units horizontally, that means that each vertex of the ABC pre-image is going to move 6 units to the right, i.e. each x-coordinate of the ABC pre-image is going to increase by 6 units and each y-coordinate of the ABC pre-image is going to remain the same.

Part B) Translate Triangle ABC -3 units vertically How are the values in the ordered pairs affected by the translation?

If the translation is -3 units vertically, that means that each vertex of the ABC pre-image is going to move 3 units down, i.e. each x-coordinate of the ABC pre-image is going to remain the same and each y-coordinate of the ABC pre-image is going to decrease by 6 units.

Part C) How could you determine the coordinates of the vertices of a translated image without using a graph?

we know that

The coordinates of the image vertices can be determined through the rule of the translation

In the part A) the translation is +6 units horizontally (6 units at right)

therefore

The rule of the translation of the pre-image to the image is equal to

(x,y) ------> (x+6,y)

Example

The coordinates of the pre-image A(-4,1)

To obtain the coordinates of the image A' apply the rule of the translation

A(-4,1)--------> A'(-4+6,1)

A(-4,1)--------> A'(2,1)

In the part B) the translation is -3 units vertically (3 units down)

therefore

The rule of the translation of the pre-image to the image is equal to

(x,y) ------> (x,y-3)

Example

The coordinates of the pre-image A(-4,1)

To obtain the coordinates of the image A' apply the rule of the translation

A(-4,1)--------> A'(-4,1-3)

A(-4,1)--------> A'(-4,-2)
